This is a simple mathematical experiment that starts with 3 points distributed equally on a circle. Then, for about 30 times, a new circle is created with a bigger radius and the amount of points incremented by the same number. Each time the incremented number is changed, the result is totally different as you see in this image.

In the previous images I used the radius of each circle to interpolate a 4 colors given palette and the angle between each point and the center of the image to shift the interpolation by a percent.
